COOKING PLATE STOVE TOP Filed May 21, 1951 Patented Dec. 15," 1931 v Yroansrvgnnrwrnnn, onfcnrcheofrrmmors it ,cooxme PLATE srov'n "T01 1Application filed May 21, 1531.; Serial Nataaoiaf y This inventionrelates tostove top cooking plateparticularly adapted, though notnecessarily limitedin its use with gas or vapor ranges, and one of theobjects of the invention is to provide an improved cooking top which isreadily removable and so shaped that the products of combustion from thei burn'er-willpass throughthe plate and circulate'across the topthereofto contact with and flow across'the bottom of" the cookingutensilorreceptacle placed thereupon.

'A further object is to provide in a plate of this character meansforcausing the products of combustion and the heated air to flowintortuous passages across the top of the plate, the plateibeing soconstructedthat overow from'the pots and kettles will run to wardthecenter of the topto be evaporated 1 before theypass through-theplateito' the y, A'further object is to provide in a plateor 7 top ofthis character meansproviding, for

the escape of theheated air and products of combustion beyond the'edgeof the kettle or pot afterpassing over the top of the plate. Totheattaininent of'these endsjand the accomplishment of other new-anduseful ob jects as will appear, the inventionconsists l 1, Figure 2; ofa plate top of this characin; the features of noveltyin substantiallythe construction, combination and arrangement of the several parts;hereinafter more fully described and claimed and shown the accompanyingdrawings illustrating this inventionfand in which If I T" Figure l 'is asectional view taken'on line ter constructed in accordancewith the prin-'ciples of this invention, and showing the sameas applied to-a-portionof a stove. Figure 2 is a'top plan view of the plate. -Figure 3 is adetail sectional on line 3'? ,Figure 2'. j

Figure 4 isa bottom plan-view of 'a portion of one corner of the plate.1 a In gas stovesof the type to which thisinvention is particularly;applicable; it. is 'customaryito provide removable grids in the top ofthe stove; and which grids are formed spaced bars and are.providedwith-unobstructed spaces located above the burners, so

view taken,

as notto interfere with the products of combustion passing therethrough,the-pots or COOklDglltGllSllS being placed'upon the grids. The sizeofthe stove and the numberof burners determines the number of: grids tobe '85 I employed. a A a A *WVith theuseof thesegrids', consider-able ofthe heat and products of combustion'from the burner are lost-astheywill'pass. freely p through the gridsand all of the products of 00 1combustion will notflbe directed against; the

bottom of the utensils l In-the, present invention these grids, aredispensed with and: in lieu -thereof there is provided one or more 7plates designated gem. erally by the reference numeral 10, according tothe-sizeof the-stove. Each of-these "platesis constructed of 'anysuitable mate- "rial and-the bodyportionthereofis provided I i with anupperfiat surface 11; In thepr'esen't form of the invention one of theplatesis shown which is rectangular in configuration and the plate isprovided with openingsfl2 therethrough of a substantial size. .Theportions of the platein proximity to these open ings l2 inclinedownwardly as at l3 from' the :flat upper surface' ll tow rd ea hw f zthopenings 12.

- Supported by the inclined portions of 1 the plate area pluralityofconcentrically ar- ;mng d ribs or projections 14 thatextend for ashortdistance'above the top of the inclined portionof the plate and theseribs are spaced 'laterally and longitudinally from each other so asto-form tortuous'p'assages'15'leading'fl across? the top of the inclinedportion ofthe -plate,"and "communicating with these passages areadditional-passages 16 formedfgin "the upper flatflsurface of the plateto open; 1 through the top thereof, so-that whena pot? .orrec eptacle 17ispilaced in position over the respective burners 18, which latter arearranged beneath theopenings 12, the prod-o ucts'of combustion from theburner and the heated air will flow through the openings 12* a andthrough the tortuous passages 15 across the topsurface' of the plate andagainst andia acrossthe bottom the utensil. The products of combustionand-heated' air wil1 'find j their escape through the'openings I 16 inthe? 99 p upper surface of the plate, and beyond the periphery of thereceptacle.

A plate of this character is removably supported upon a ledge or flange19 encompassing the usual opening in the top of the stove designatedgenerally by the reference numeral 20, and projecting below the lowerface of the plate 1Q at suitable points, and as is usual in castings,are lugs or projections 21, which latter may be filed or shaped so as toovercome the imperfections in casting and to permit the plate to restfiat upon the flange or flanges 19. These lugs or projections 21 may bearranged at any point about the circumference of the plate and on thelower face thereof and may be of any desired width and length.

The plate is provided with attentional openings 22 therethrough for theescape of heated airfrom beneath the plate and may also be provided withan opening therethrough disposed above the usual pilot light 'on thestove. I v p It Will be manifest that with a plate of this characterconsiderable heat will be radiated beneath the bottom thereof and inorder to provide means whereby this radiated heat may be employed in theheating of the utensil, there may be provided in the bottom of thegrooves or spaces formed between the respectiveseries of projections14;, openings 2 deny .deslred size and of any desired number, Theseopenings may be located in proxim-ity to the openings formed between theproximate ends of adjacent projections or may be otherwise disposed withrelation thereto, and a circulation of the heated air through'suchopenings from beneath the plate .will be induced by the circulation ofthe air on'the top of the plate through the tortuous passages 15.

If desired anupright flange 25 may encompass the openings 12 to assistin directing the products of combustionthrough the .openings 12.

By reason of the tortuous passages and of the openings 24, a circulationof the heated air and products of combustion across the top of the platewill be insured and the heated air will escape through the openings 16in the top surface of the plate and will be thereby. prevented frombeing directed back against thefiame of the burner 18.

While the preferred form of the invention hasbeen herein shown anddescribed,it

is to be understood that various changes may be made in the details ofconstruction and in the comblnation and arrangement of the severalparts, within the. scope of the claims, "2150 without departing from thespirit of this invention. a
